Volcanoes

Front

What are stratovolcanoes primarily made of?

Back

Stratovolcanoes are primarily made of layers of lava, ash, and other volcanic materials.

Front

What is the definition of a dormant volcano?

Back

A dormant volcano is one that hasn’t erupted in the last 10,000 years but could still erupt in the future.

Front

Describe the type of eruptions associated with shield volcanoes.

Back

Shield volcanoes are characterized by quiet eruptions that produce low-viscosity lava.

Front

What is a cinder cone volcano?

Back

A cinder cone volcano is a steep, conical hill formed from the accumulation of volcanic debris, primarily cinders.

Front

What is the main difference between stratovolcanoes and shield volcanoes?

Back

Stratovolcanoes have steeper profiles and are made of alternating layers of lava and ash, while shield volcanoes have gentle slopes and are primarily built from low-viscosity lava.

Front

What type of volcanic activity is associated with stratovolcanoes?

Back

Stratovolcanoes typically have explosive eruptions due to the high viscosity of their magma.

Front

What is the significance of the term 'active volcano'?

Back

An active volcano is one that has erupted recently and is likely to erupt again.

Front

How can you identify a cinder cone volcano?

Back

Cinder cone volcanoes can be identified by their steep slopes and circular or oval shape, often with a bowl-shaped crater at the summit.

Front

What are the hazards associated with volcanic eruptions?

Back

Hazards include lava flows, ash fall, pyroclastic flows, volcanic gases, and lahars.

Front

What role does magma viscosity play in volcanic eruptions?

Back

Magma viscosity affects the explosiveness of an eruption; high-viscosity magma tends to trap gases, leading to more explosive eruptions.
